Abstract
【解決手段】 2,3,3′,4′−オキシジフタル酸無水物及び3,4,3′,4′−オキシジフタル酸無水物を必須とする酸二無水物混合物とジアミンとから得られる可溶性ポリイミド。
【選択図】 なし
Description
(1)酸二無水物とジアミンとから得られるポリイミドであって、酸無水物が30〜90モル%の式(1)で示される2,3,3′,4′−オキシジフタル酸無水物と70〜10モル%の式(2)で示される3,4,3′,4′−オキシジフタル酸無水物の混合物であり、有機溶剤に可溶であることを特徴とするポリイミド;
(5)(1)〜(3)のいずれか1項記載のポリイミドの前駆体であるポリアミド酸;及び
(6)(5)記載のポリアミド酸を含有する溶液
である。
窒素ガス導入管、冷却管、温度計、撹拌機を備えた四つ口フラスコに4,4′−オキシアニリン(4−ODA)20.024g(0.100モル)及びジメチルホルムアミド200.2gを入れ、窒素ガスを流しながら溶解し、5℃に冷やす。次に、2,3,3′,4′−オキシジフタル酸無水物/3,4,3′,4′−オキシジフタル酸無水物のモル組成が6/4のオキシジフタル酸無水物混合物31.021g(0.100モル)を添加し、一晩撹拌する。得られたポリアミド酸溶液に無水酢酸30.6g(0.30モル)及び無水ピリジン3.2g(0.04モル)を15分かけて滴下し、8時間室温で撹拌する。得られたポリイミド溶液をメタノール中に注ぎ、ポリイミドを析出し、乾燥する。乾燥後、1,3−ジオキソラン溶液に再度得られたポリイミドを溶解し、15重量%濃度のポリイミド溶液とした。
実施例1の酸無水物成分を2,3,3′,4′−オキシジフタル酸無水物/3,4,3′,4′−オキシジフタル酸無水物のモル組成が7/3のオキシジフタル酸無水物混合物24.817g(0.080モル)と3,4,3′,4′−ビフェニルテトラカルボン酸無水物(BPDA)5.884g(0.020モル)に替えて、同様に可溶性ポリイミドの溶液を得た。得られたポリイミドの熱特性結果を表1に示す。

実施例1の酸無水物成分を2,3,3′,4′−オキシジフタル酸無水物/3,4,3′,4′−オキシジフタル酸無水物のモル組成が8/2のオキシジフタル酸無水物混合物24.817g(0.080モル)とピロメリット酸無水物(PMDA)4.362g(0.020モル)に、4,4′−オキシアニリンを1,3−ビス(3−アミノフェノキシ)ベンゼン(APB)29.233g(0.100モル)に替えて、同様に可溶性ポリイミド溶液を得た。得られたポリイミド膜の熱特性結果を表1に示す。
実施例1の酸無水物成分を2,3,3′,4′−オキシジフタル酸無水物/3,4,3′,4′−オキシジフタル酸無水物のモル組成が5/5のオキシジフタル酸無水物混合物31.021g(0.100モル)に、4,4′−オキシアニリンを1,3−ビス(4−アミノフェノキシ)ベンゼン(TPE−R)29.233g(0.100モル)に替えて、同様に可溶性ポリイミド溶液を得た。得られたポリイミド膜の熱特性結果を表1に示す。
実施例1の酸無水物成分として2,3,3′,4′−オキシジフタル酸無水物24.817g(0.100モル)のみと4,4′−オキシアニリン(4−ODA)20.024g(0.100モル)を用いて,同様に可溶性ポリイミド溶液を得た。得られたポリイミド膜の熱特性結果を表1に示す。
尚、2,3,3′,4′−オキシジフタル酸無水物と3,4,3′,4′−オキシジフタル酸無水物のモル比が20:80の場合、及び0:100の場合には、実施例1と同様にして得られたポリイミドは溶媒に不溶であった。
